RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 270,521, dated January9, 1883.

, Application filed April 25,1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. WATERS, of Muskegon, in the county ofMuskegon and State ot'.l\lichigan, haveinvented a new and use fulImprovement in Railroad-Frogs, of which the following is a full, clear,and exact description.

My invention relates to the construction of frogs for railroad-switches,and has the object to obtain durability and to avoid the liab lity ofbreaking the flanges of the wheels while passing over the frog.

The invention consists in a filling of. cast metal applied between theside rails of the frog and around the point, as hereinafter describedand claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan view of a frog of my improved construction. Fig.2 isa transverse section on line a: as of Fig. 1.

A is the frog-plate, to which the side or guard rails, or a,areriveted,as is also the point B between the guard-rails. G is a block orfilling of cast metal, applied between the guardrails a a and around thepoint B. This filling is applied by pouring the molten metal so that theblock fits snugly beneath the heads of the guard-rails and to theflanges, and is thus retained securely in place. In pouring the metal itbecomes chill-hardened by the surrounding iron, and is thereby rendereddurable. The

filling is also immovable, from the fact that it fits tightly.Consequently there is no rattle or movement when the train is passingover the frog. All bolts usually required for securing the filling-pieceare dispensed with, and consequently the labor of keeping the boltstight to prevent their displacement is avoided.

The guard-rails and point will not be riveted to the plate A beneath thefilling-piece, so that in case one guard-rail should wear more rapidlythan the other it can be removed by cutting out the rivets and anotherrail put in its place.

I am aware that a method of filling blocks into railroad-frogs hasbefore been described, in which a point of wrought metal being broughtto a welding-heat, the melted metal is then cast thereon, and wings orguard-rails afterward bolted thereto. That is not my invention; but

What I claim, and wish to secure by Letters Patent, is

In railroad-frogs, the combination, with the bed-plate A, having theguard-rails a and the point B, bolted or riveted thereto, of the block0, consisting of metal chilled by being poured while melted between saidpoint and guardrails while they are cold, said metal not uniting withthe guard-rails or point, but leaving them free to be renewed, as shownand described.
